How to download API3 (API3) historical data
- Open the Data Shop — it lands on the most-recorded API3 instrument; every other instrument on this page links straight to its own day calendar.
- Pick a UTC day in the calendar. Each day is one file with every trade, order-book update and quote the venue published — the shop shows the day's candle and file size before you buy.
- Try a free sample day first — one complete day, same schema, no sign-up.
- Check out as a guest — pay by card, no account, no sales call — and the file downloads immediately at €1 per instrument-day. Buying many days? Select them across the calendar or use the scanner bulk-add.
- Need CSV or Parquet instead of the native tick file? Append
?format=to any download — see the formats overview. Coding agents can do all of this through the MCP server.

API3 (API3) in real time — live order books and trades by the UTC day
API3 streams live on Binance USDT-M, Binance Spot, Coinbase Spot and OKX — order book, top of book, trades, mark price, index price, funding rate and liquidations over WebSocket (JSON or SBE), captured at each venue and delivered at our London, Frankfurt, Ashburn, Ohio or Tokyo endpoints over dedicated lines (Binance and OKX from Tokyo at London, Frankfurt, Ashburn or Ohio; Coinbase from Ashburn at Ohio or Tokyo). Buy one API3 instrument or the whole market by the UTC calendar day and connect with one API key.

Coinbase lines: ~4.6 ms Ashburn → Ohio and ~67.7 ms Ashburn → Tokyo — one-way line latency from the site where the venue is captured to our endpoint — the venue's own latency and the on-ramp to your client come on top.

Why buy API3 data here
Four things every page on this site is built on — and the reason the numbers above exist at all.
We record everything
The complete public feed of each venue as it was published: every Level-2 snapshot and update at the venue's full book depth, every trade with its aggressor side, every quote, funding, mark-price and liquidation event — for every instrument the venue lists, every UTC day since we added the venue. Nothing sampled, no top-N cut, no on-demand capture.
Institutional grade
Captured co-located at the venue with the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain that makes any gap visible, and one normalized schema across 35+ venues — the same capture our own high-frequency trading engine and enterprise feeds run on.
€1 per instrument-day
Any instrument-day is €1, series-day bundles start at €1 — no subscription, no minimum order, no tiers to unlock. Credit packs lower the effective price and never expire, and every venue has free full-day samples to test against first.
Self-service for everyone
Pick the days in the Data Shop, pay by card as a guest and download immediately — no sales call, no enterprise contract, no KYC. Coding agents buy the same files through the MCP server, and the free Agent Skill teaches them the format.

Per-venue and per-pair daily series are in the analytics.
Do you have every API3 pair, or only the big ones?
Every API3 instrument on every venue we record, every UTC day since it was added — the 18 venues and 30 pairs on this page are the archive's full list, not a curated top-N, each captured as the complete feed at full book depth.
